Common questions about tools, API, privacy and responsible use
Is 4DevTool free?
Yes. The public web tools are free to use and do not require an account.
What is 4DevTool used for?
4DevTool is used for development, QA, demos, testing, automation, formatting data, validating inputs, creating mockups and working with browser-based developer utilities.
Are generated documents or identifiers real?
No. Generated values are synthetic test data. Some values may be mathematically format-compliant, but they are not official records and must not be used as real documents, real identity data, real registrations or for any illegal activity.
Does 4DevTool store tool inputs?
Most tools are designed to process values in the browser whenever possible. 4DevTool does not intentionally store tool inputs as user records. Technical logs, analytics, advertising cookies and contact emails are described in the Privacy Policy.
Does the API require an API key?
No. Public API endpoints documented in the API Docs can be used without an API key, subject to reasonable use and possible rate limits.
Can I use synthetic data in production?
Synthetic data is intended for non-production workflows such as QA, development, staging, demos and automation. Do not use generated personal, company, banking or document-like values for real registrations, contracts, purchases, identity checks or official processes.
Can I suggest a new tool?
Yes. Send suggestions, bug reports or corrections to contact4devtool@gmail.com.
